Referring to the accompanying drawings, I have used the numeral 10 toindicate the arched back of the machine-frame, preferably made of ametal tube. At the forward end thereof is a steering-head 11 and 'at theother end is the rear fork 12. Mounted upon thepart 1.0 is a seat 13,and a short distance in front of the seat is a tubular upright 14.Pivoted to the ends of the rear fork 12 are the runners 15, and mountedin the steering-head 1 1 is the upright rod 16, having the runner 17pivoted at its lower end and having the crosshead 18 fixed to its upperend above the steering-head and shaped to receive the operators feet, sothat the vehicle may be steered by the feet of the operator. Formed onthe steering-head 11 are the lugs 19, in

A spring 21 is mounted upon the brake-rod between the lugs to normallyhold the brakerod elevated. The upper end of the brake rod projects to aposition where the operator may readily place his foot thereon, so thatthe brake-rod may be pushed downwardly to engage the surface upon whichthe runner 17 rests.

I have provided the following means for propelling the velocipede: Atthe top of the upright 14 is a cross-head 22, and at the bottom of theupright 14 is a cross-head 23. Mounted in these cross-heads on oppositesides of the upright 14 are two parallel vertical shafts 24. Anoperating-handle 25 is attached to the upper end of each of the verticalshafts 24 by being screwed into a T 26, which T rests upon the top ofthe cross-head 22. At the lower end of each vertical shaft 24 is apinion 27, said pinions secured to the shafts by the set-screws 28 andarranged in mesh with each other, so that the vertical shafts arerotated in unison. At the lower end of each of the vertical shafts 24 isan arm 29, projected outwardly therefrom and formed with a journal 30 atits outer end portion and a head 31 beyond the journal. This journal isinserted in a block 32, provided with an opening to receive it, and saidblock is provided with a vertical opening intersecting the opening toreceive the journal, said vertical opening designed to receive a pin 33.This block 32 is inserted in a yoke shows a detail View illustrating themeans for which is slidably mounted the brake-rod 20.-

34, having an opening large enough to per mit limited movement of theblock on the pivot-pin 33, which pin passes through the yoke. On theinterior of the yoke is a screwthreaded nut 35, and an arm-36 isinserted in the yoke and screwed into said nut. In this way the arm 29is connected with the arm 36 in such a manner as to permit a limiteduniversal movement between said parts. At the rear end of the arm 36 isa yoke 37, to which the arm 36 is pivoted by the pin 38.

ver. The lever members at the opposite sides of the front end areinserted between the yokes 37 and pivotally connected therewith by thepivot-pins 40. Connected with the same pivot-pins are two short levers41,

extending forwardly and toward each other and pivoted to a plate 42.These levers 41 incline away from the adjacent lever mem bers of thelazy-tongs lever at slightly greater angles than the lever member of thelazytongs lever proper incline relative to each other. The plate 42 isconnected with alink 43, which in turn is pivoted between the lugs 44 atthe rear of the cross-head 23. The rear end of the link 43 is permittedto move up and down, but prevented from moving laterally by the lugs 44by the arrangement of the parts ust described. A rearward movementimparted to the operating-handles will cause "the lazy-tong's lever "tobe moved to its extended position, and a'forward movement-of the handleswill bring the lazy-tongs lever to its folded position. The lazy-tongslever members 41 will prevent the rear end of the lazy-tongs lever fromswinging laterally,and

on account of the difference in the inclination of the members 41 andthe other members of the lazy-tongs lever it is easier to start theextending movement of the lazytongs lever than if the members 41 wereparallel with the other members.

Furthermore, by the arragement of the parts connecting the arms 29 withthe lazy -'tongs lever the lever may'be'swung up and down and may beextended or folded readily when at any position of its swingingmovement. In this connectionI have provided an improvedba'llbearingjoint for connecting the j oints of the lazy-tongs levers, as followsThe leversproper are preferably of tubular-construction, and on theupper member at the joint'is a disk-45, formed with an annular groove 46on its under surface and with a concentric opening. On the other memberat the oint is a disk 47, formed with a ball-bearing'groove 48 in itsupper surface and a ball-bearing-groove 49 in its under surface andalso'formed with a central opening. Beneath the disk 47 is -athirddisk50, not connected with either of the lever members and formed with aball bearing ings of them, and a nut 53 is provided at the lower end ofthe bolt. A set of bearing-balls 54 is placed between the grooves 46 and48. In this way the lever members are firmly held in the same plane andyet the members may move relative to each other with a minimumoffriction. At the rear end of the lazy-tongs lever are two levermembers 56, projected rearwardly and toward each other at angles whichincline away from the adjacent lazytongs-lever members greater than theother The numeral 39 indicates a lazy-tongs le' lazy-tongs membersincline relative to each their rearends to the yoke 57 by means of thepivot-pin 58. Fixed to the yoke 57 is a rod 59, projecting downwardlyand rearwardly. The device for engaging the surface over which thevehicle travels is pivoted to this rod 59 and will be described indetail hereinafter. On top of the yoke 57 is a-lug 60, and a guide-rod61 is fixed thereto and extends straight forwardly over the center ofthe lazytongs lever. tion of two of the cross members of the lazytongslever is a guiding-cyinder 62, having said guide-rod 61 slidinglymountedin it. By means of the said guide, comprising the rod 61 and thecylinder 62, therod 59 is firmly v held in line with the center'of thelazy-ton s lever, and the-movement to'extend and fo d the lazy-tongslever is not impeded.

I have provided means for automatically folding the lazy-tongs lever, asfollows: Fixed to the forward ends of the yokes 34 are the "contractiblecoil-springs 63, extended forwardly and inwardly and attached to theframe member 10. Thesesprings are of sufficient resiliency to throw thelazy-tongs lever to its folded position when the operator releases thehandles. I have also provided means by which the rear endof thelazytongs lever is forceddownwardly at the commencement of its extendingmovement and is forced upwardly at the commencement of its foldingmovement, so that the means for engagin the surface over which thevehicle is trave ing will stand in contact with said surface only duringthe effective portion of the movement of the propelling device and willbe held out of contact with the surface over which the vehicle istraveling when the propelling device is at rest.

The numeral 64 indicates an arm having at one end a clamp 65, designedto encircle one of the upright shafts 24.' Between the clamp and theshaft is a yielding washer 66, and the clamp 65 is provided with lugs67, held toward each other by a bolt 68. Pivoted to the outer end of thearm'64 is an arm "69.

" is moved forwardly and rearwardly inunison with the operating-handles.Attached to the plate '70 is a rod 71. extended rear- Mounted upon thecentral porwardly and pivoted to a bell-crank lever 72, which in turn isfulcrumed to a support 73 on the machine-frame. The'other end of thebell-crank lever is pivoted to an arm 74, pivoted to the rear endportion of the arm 43. An extensible spring 75 is placed on the rod 71,with one end in engagement with the frame and its other end 'inengagement with a nut on the rod 71. Assuming that the handles 25 aremoved rearwardly, they will carry with them the plate 70 and the rod 71,and this movement will compress the spring 75. The said rod 71 willoperate upon the bellcrank lever 72, and this will force the rod 74downwardly and cause the runner to be brought into engagement with thesurface over which the velocipede is traveling, and it will stay incontact therewith during the entire rearward movement of the handles 25.In this connection it is to be noted that dur ing part of this rearwardmovement of the operating-handles the arms 64 may slide relative to theshaft 24 on account of the yielding washers 66, as the rearward movementof the part 71 is limited by the runner striking upon the solid surfaceon which the vehicle is traveling. Then when the handles 25 havecompleted their rearward movement and are released they will be movedforwardly by the springs 63, and at the same time the rod 71 will bemoved forwardly by the spring 75, the said spring being of sufficientresiliency to elevate the runner and its connected parts from thesurface as soon as the lazy-tongs lever begins its folding movement. Bymeans of these parts it is obvious that the runner 'is thrust intoengagement with the surface at the commencement of its operative strokeand is elevated and held above the surface at the commencement of itsreturn stroke. The spring 75 practically counterbalances the weight ofthe lazy-tongs lever and runner, and the movement of the arms 64 on theshafts 24 is limited in one direction by the runner striking upon thesurface and in the other direction by a nut on the rod 71 striking theframe. In this connection it is to be noted that the lazy-tongs lever isnormally held in its folded position by the springs 63.

The device at the end of the rod 59 for engaging the ice or othersurface over which the vehicle passes may consist of a sharpenedprojection 76, such as shown in Fig. 6, which projection may be attacheddirect to the lower end of the rod 59. However, I prefer to use thedevice illustrated in detail in Figs. 8 and 9 and comprising a runner 77pivotally mounted between the arms 78, which arms overlap the sides ofthe runner and are piv otally connected therewith by the pin 79. Abovethe pin 79 the arms 78 are provided with segmental slots 80,, arrangedconcentric relative to the pin 79. The upper ends of the arms 78 areformed with openings 81 to receive a pin 82 for pivotally connectingthem with the arm 59. The rear ends of the arms 78 project beyond therear end of the runner 77, and a sharpened projection 82 is fixedbetween them, extending rearwardly and downwardly. Rotatably mounted inthe runner 77 above the pin 79 is a pin 83, the ends of which projectthrough the slots 80. Attached to the projecting ends of the pin 83 arethe pointed levers 84, which levers project downwardly and are of suchlength that they will project slightly below the lower surface of therunner when in position at right angles to the longitudinal axis of therunner. On the upper end of each lever 84 is an extension 85, and-fixedto the arms 78 are the limiting-pins 86. These parts are so arrangedthat when the runner 77 is restingupon the surface over which thevehicle is advancing and is being moved forwardly the lower ends of thelevers 84 will strike the surface and will be moved rearwardly relativeto the runner, thus mov ing the extensions 85 forwardly, so that theywill strike the pins 86 with sufficient force to elevate the pointedprojection 82 and hold it in its elevated position. Assuming, however,that the rod 59 is moved rearwardly and downwardly with considerableforce, then it will slide the runner 77 rearwardly, and the lower endsof the levers 84 will enter the surface upon which they are resting andform a pivot-point upon which the levers 84 will turn until theextensions strike the opposite set 1 of pins 86 and result in forcingthe pointed projection 82 downwardly and into the surface over which thevehicle is advancing.

Hence when the runner 77 is being moved forwardly by the arm 59 thepointed projection will be held in an elevated position; but as soon asthe arm 59 is forced rearwardly the pointed projection will be thrustinto the surface, so that the vehicle may be pushed forwardly by thepropelling mechanism.

In practical use the operator is seated in the seat 13 and his feet restupon the steering-bar 18. The operator grasps the handles 25, and bymoving them rearwardly the lazytongs lever is extended and the pointedprojection carried at the rear end thereof is forced into the surface onwhich the device is resting and the vehicle is moved forwardly over thesurface on which it is resting. By arranging a lazy-tongs lever that issusceptible of extending to a considerable degree in the rear of themachinesay, for instance, six feetan operator upon the machine standingon relatively smooth ice may with a second operation of the handles givethe machine a forward impetus sufficient to carry it on the runners adistance of more than a hundred feet. As soon as'the thrusting movementis completed the operator permits the springs to return the handles andat the same time the rear end of the lazy-tongs lever is automaticallyelevated and held out of contact with the ice. When the vehicle is trav-&

eling over ice, the operator may by rapid movement of the handles extendthe lazytongs lever at such speed that the pointed projection willengage the ice and an additional forward impetus be given to the vehicleeven when the vehicle is traveling at a high speed. Hence a relativelyhigh speed may be maintained without a regular uniform working of thehandles, as they need be operated only when the speed begins todecrease.
